title: Click-reagent version of Sonogashira coupling protocol to conjugated fluorescent alkynes with no or reduced homocoupling.
abstract: A click-reagent version of the Sonogashira-coupling protocol has been developed. Diarylalkynes with donor and/or acceptor substituents have been synthesized via this protocol at moderate to excellent yields and with no or drastically reduced quantities of undesired homocoupled side products. This protocol is green-solvent compatible, air-insensitive, and effective under microwave conditions.
